This is my rig.
I started with a Raystorm EX 480. Great temps for CPU. Low 40's under load.
GPU's were 80's pushing 90 on load.
I decided to add all 3 GPU's to my loop.
Current temps have now flipped.
CPU is pushing 90 under load and GPU's are 60.
Two thoughts and I am not sure which is better.
1. Add an additional radiator to the loop, I am thing 240mm or 360mm by 30mm and adding it to the front of my 900D case where the 3 fans exist already.
2. Make a complete separate loop again using a 240/360 rad and d5 pump and cylinder resouvour for the CPU.
My own thought is just adding the additional rad should be enough.
Please provide your thoughts because I just don't know for sure.
